Gr. ses, thus rendered in Matthew 6:19, 20; Luke 12:33. Allusion is thus made to the destruction of clothing by the larvae of the clothes-moth. This is the only lepidopterous insect referred to in Scripture.

By the Hebrew word we are certainly to understand some species of clothes-moth (tinea). Reference to the destructive habits of the clothes-moth is made in (Job 4:19; 13:28; Psalms 39:11) etc. (The moth is a well-known insect which in its caterpillar state is very destructive to woollen clothing, furs, etc. The egg of the moth, being deposited on the fur or cloth, produces a very small shining insect, which immediately forms a house for itself by cuttings from the cloth. It east away the nap, and finally ruins the fabric. There are more than 1500 species of moths.

Motheat

MOTH'EAT, verb transitive [moth and eat.] To eat or prey upon, as a moth eats a garment.

The superiority of the Hebrew over all contemporaneous systems of legislation and of morals is strongly shown in the higher estimation of the mother in the Jewish family, as contrasted with modern Oriental as well as ancient Oriental and classical usage. The king's mother, as appears in the case of Bath-sheba, was treated with special honor. (Exodus 20:12; Leviticus 19:3; 5:16; 21:18,21; 1 Kings 2:29; Proverbs 10:1; 15:20; 17:25; 29:15; 31:1,30)

Mother

MOTHER, noun [Latin mater, mother; matrix, the womb; materia, matter, stuff, materials of which any thing is made. We observe that in some other languages, as well as in English, the same word signifies a female parent, and the thick slime formed in vinegar; and in all the languages of Europe here cited, the orthography is nearly the same as that of mud and matter. The question then occurs whether the name of a female parent originated in a word expressing matter, mold; either the soil of the earth, as the producer, or the like substance, when shaped and fitted as a mold for castings; or whether the name is connected with the opinion that the earth is the mother of all productions; whence the word mother-earth. We are informed by a fragment of Sanchoniathon, that the ancient Phenicians considered mud to be the substance from which all things were formed. See Mud. The word matter is evidently from the Ar. madda, to secrete, eject or discharge a purulent substance; and I think cannot have any direct connection with mud. But in the Italian, Spanish and Portuguese, the same word madre signified mother and a mold for castings; and the northern languages, particularly the German and Danish, seem to establish the fact that the proper sense of mother is matrix. Hence mother of pearl, the matrix of pearl. If this word had its origin in the name of the earth used for the forms of castings, it would not be a singular fact; for our word mold, in this sense, I suppose to be so named from mold, fine earth. The question remains sub judice.]

1. A female parent; especially, one of the human race; a woman who has borne a child; correlative to son or daughter.
